Notice how, after all the green disappears over land, there is still green over Lake Michigan. That’s because birds who find themselves migrating over water at sunrise have no place to land. This next image shows what happens on the radar as these birds head for the closest shore:
So, our neighborhood should have some newly arrived migrants this morning, and parks and neighborhoods along the Lake Michigan shoreline should be packed with newly arrived birds. It will be interesting to read today’s online reports from places like Montrose Park in Chicago.
As always, we’ll let you know what we see and hear in our neighborhood.
Note added at 7:45 a.m. the same day: So far we have heard no warblers singing in our yard. We did just hear a Gray Catbird singing one or two backyards to the south — they had been gone from our neighborhood for several days.
Note added at 9:45 a.m. the same day: The day’s first report on Montrose birds has been posted on the Illinois birders e-mail list. It stated, “Montrose was pretty good this morning, finally. Obviously last night’s southwest winds did some good.” The report listed 21 species of warblers. (A report from yesterday listed 17 species.)
